Molecular epidemiological characteristics of human rhinovirus in adults with upper respiratory tract infection in Nanjing / 中华微生物学和免疫学杂志

Objective:To analyze the clinical and epidemiological features of human rhinovirus (HRV) infection in adult patients with upper respiratory tract infection (URTI) in Nanjing.Methods:Epidemiological data of adult patients with URTI in Nanjing from October 2021 to September 2022 were collected. Clinical specimens were collected and subjected to quantitative reverse transcription polymerase chain reaction (qRT-PCR) for the detection of 14 common respiratory viruses. The VP4/VP2 genes in HRV-positive samples were amplified and sequenced. Then a phylogenetic tree was constructed.Results:A total of 399 pharyngeal swabs were collected from patients with URTI. The overall positive rate of respiratory viruses was 28.07% (112/399) with HRV accounting for most at 9.52% (38/399). Thirty-seven VP4/VP2 sequences were successfully obtained from the 38 HRV-positive specimens. Three genotypes involving 25 serotypes were identified with 13 strains belonging to HRV-A, 14 belonging to HRV-B, and 10 belonging to HRV-C. The three genotypes of HRV showed alternate prevalence or co-prevalence.Conclusions:HRV was the main pathogen causing URTI in adult patients in Nanjing from October 2021 to September 2022, and three genotypes of HRV-A, B and C were prevalent alternatively or together.

Analysis of hope level and influencing factors of infertile patients with first or repeated IVF-ET / 中华健康管理学杂志

Objective:To explore the hope level and influencing factors of infertile patients with first or repeated in vitro fertilization-embryo transfer (IVF-ET).Methods:Female patients receiving IVF-ET treatment during January to June, 2019 in reproductive Medicine Center, Ruijin Hospital, Shanghai Jiaotong University School of medicine, were enrolled in this study. All patients were divided into first and repeated cycles (≥2 cycles), then a questionnaire survey was conducted. The questionnaire included demographic information, Herth hope index (HHI) scale, Locke-Wallace short marital-adjustment test scale and social support rating scale. Multiple linear regression was used to analyze the associated influencing factors of hope level.Results:A total of 251 IVF-ET patients were recruited in the study, including 142 (56.6%) in the first cycle and 109 (43.4%) in the repeated cycle. The HHI score of the repeated cycle was significantly lower than that of the first cycle [(32.0±3.3) vs (36.0±3.1) points] ( P<0.001). Multiple linear regression analysis indicated that repeated IVF-ET was independently negatively correlated with HHI, with a standardized coefficient β of -0.406 ( P<0.001). While living in a city ( P=0.013), high monthly income ( P=0.026), high degree short marital-adjustment test ( P=0.006) and social support rating ( P=0.002) were independently positively correlated with HHI. Conclusions:Repeated IVF-ET treatment patients have a significantly lower HHI score. The residence, monthly income, marital-adjustment, and social support are significantly associated with hope level.

Anti-leucine-rich glioma-inactivated protein 1 and glutamic acid decarboxylase 65 antibodies double-positive autoimmune encephalitis complicated with vitiligo: a case report / 中华神经科杂志

Autoimmune encephalitis (AE) refers to a kind of encephalitis mediated by immune mechanism, which is one of adult symptomatic epilepsy due to unknown etiology. Early recognition has certain difficulty. AE patients with multiple antineuronal antibody co-existing are relatively rare. Clinical symptoms are more complex and variable, and can involve a wider range of immune system. A case of temporal lobe epilepsy with anti-leucine-rich glioma-inactivated protein 1 and glutamic acid decarboxylase 65 antibodies double-positive AE complicated by vitiligo and diabetes is reported. After immune shock and continuous immunotherapy, the patient completely recovered from encephalitis and diabetes, and vitiligo was improved obviously.

OBJECTIVE:To investigate the intervention effects of (E)-4-[2-(4-chlorophenoxy)-2-methylpropanoyloxy]-3-me-thoxyphenyl acrylic acid (AZ) on fat accumulation in human hepatoma HepG2 cells. METHODS:Oleic acid was used to induce fat accumulation in HepG2 cells in logarithmic phase for establishing models of fat accumulation,which were divided into a model group,a positive control group(100 μg/ml simvastatin),and the groups of 15.63,31.25,62.5,125,250,500 and 1 000 μg/ml AZ,and a normal control group was set up. MTT method was used to detect the survival rates of all groups of cells,kit was per-formed to determine the contents of triglyceride (TG) in all groups of cells and calculate the clearance rates,and oil red O stain was conducted to observe the lipid droplet morphology of all groups of cells. RESULTS:Compared to the normal control group, the model group and the groups of 15.63-125 μg/ml AZ demonstrated no obviously different survival rate of cells,and the groups of 250-1 000 μg/ml AZ had lower survival rate of cells. There was statistically significance (P<0.05). The contents of TG in the cells of the model group were higher than those in the cells of the normal control group. The positive control group and the groups of 62.5 and 125 μg/ml AZ had lower contents of TG in the cells compared to the model group,showing a TG clearance rate of (28.58 ± 0.15)%,(14.51 ± 0.09)% and (29.72 ± 0.16)% respectively. There was statistically significance (P<0.01 or P<0.05). There were much more lipid droplets in the cells of the model group than in those of the normal control group. The lipid droplets in AZ groups gradually became less in quantity and smaller with the increasing in drug concentration. CONCLUSIONS:AZ has inter-vention effect on fat accumulation in HepG2 cells.
